Hi Tradesman thanks for responding so quickly, I just replaced the power supply as the 12V rail was gone ....computer booted up fine and worked well for a week or so. We stream music and upon rebooting to get my resources back it wouldn't boot up at all. Have 3 HD's with all new cables tried resetting the CMOS to no avail....just so you know after new PS installed did go in and reset the BIOS .....this is a large rack computer built mainly for Audio.
Thanks,
Icey
